Does it or doesn't it support multiple sample rates?

Ok.

It support only 8kHz rate. I'll remove define and use SNDRV_PCM_RATE_8000 only in gtm601_dai struct.
Thanks and BR.

I was more commenting on the fact that the comment immediately above says that the sample rate is determined automatically which suggests that multiple sample rates are supported.

OK I see. Checked with gtm601 datasheet max master clock is 2.048MHz so it is 8kHz LRCLK. Sorry for confusing comment.
